Scientists about the “killer corona” virus: go from snakes popular market in China

Scientists have revealed that the new deadly corona virus, which has spread to several countries from the Chinese city of Wuhan, has been transmitted to humans from snakes sold outdoors in a market in the Chinese city of Wuhan, and scientists at Peking University believe that 2019-nCoV, the SARS-like virus that infected More than 500 people around the world have killed 17 patients, consisting of a mixture: one that affects bats and another, a completely unknown corona virus.

Russia Today site reported that scientists said that the genetic material of the two recombinant, picked up a protein that allows viruses to bind to certain polarized cells, including human cells, and when they analyzed genetics of strains, which affect different host animals, they found that the snakes released the most Similar to Corona virus, it is likely that it provided a “reservoir” so that the viral strain would become stronger and more frequent.

By selling it alongside live koala, mice, and others at the Huanan Seafood Market in downtown Wuhan, which is now believed to be the epicenter, snakes are likely to be a stepping stone for the virus to start infecting humans.

“The results from our evolutionary analysis indicate for the first time that the snake is the most likely wild animal to accommodate 2019-nCoV,” the authors wrote in the journal Medical Virology. The new information obtained from our evolutionary analysis is extremely important to effectively control the outbreak of the disease caused by pneumonia caused by 2019-nCoV. ”

There are different strains for most types of the virus, but not all of them are in all places, and not every strain can infect all types.

In the study, the Beijing team arranged genes for 272 strains of the Coronavirus. Also, the new strain that spread from China is only the seventh version of the Corona virus known to infect humans.

The deadly coronavirus includes the severe acute respiratory syndrome (SARS), which first appeared in China in 2003, and the Middle East Respiratory Syndrome (MERS), and the new study found that the genetic material of the new corona virus, RNA, appears to be a crossed strain of a breed known to have a bat.

The type that the virus can infect depends on the proteins on the surfaces of its cells and whether it can bind to receptors on the surfaces of other animal cells.

Even somewhere along the evolution path, 2019-nCoV picked up protein switches, or the protein that unlocked the lock to give it access to snakes. From there it multiplied and transformed in a way that gave it the transition to humans, who were shopping from the Huanan seafood market, and the market has since been closed and has been described by local authorities as a “zero point”.

It is worth noting that the dangerous virus has infected (so far) hundreds in China, South Korea, Japan, Thailand, Hong Kong and the United States.
